Be it-"knownthat I, EDWIN-R. SMITH, a citizen of the United States, residing at Fitchhurg, in the county of' ld o'rcester and State of Massachusetts, have inventedanew and useful Stop 'Motion' for Addressing Machines, of which thefollow' ing is'a speci fication.

This invention relates particularly to a machine for addressing magazine's, periodicals or other articles. tis customary to'use such machines for addressing magazines to their suhscriptionlists and it is very essential that one magazine and only one should he addresse-dby each stencil'inthe list. If, for any reason, the supply ofmagaz-ines fails or a magazineis not fed forward to addressing position at the proper time, the stencil feed should'be: immediate-1y stopped. It is the general object of my "invention to provide improved devices for thus suspending the stencil feed' upon failurefto resent a magazine in addressing position. With this general object in-view,' my invention in a preferred form cil feeding'mechanismcontrolled as' to its operation by the presence or absence of a magazinein addressing position.

A further feature of my inventionrelates to the provi'sion' of actuating mechanism for the stencil feed, together with-means, for disj abling the actuating 'm'echanism on failure to present a magazine 'in addressing position. r j f A preferred form of my invention is showninthe drawings in which 1 Fig. 1. is a front elevation of parts of an addressing machine," showing the st-encil feed; 7 I Fig. 2'is a side elevation of parts of the addressing machine, showing particularly the stop motion mechanism; I i Fig. 3 is an enlarged sideelevation of the stop motion;- Figs. 4 and 5 of a detachable connection in feed;

are enlarged front elevations the stencil Fig. 6 is a detail plan view, looking inthe direction of the arrow 6 in Fig. 3; and V Fig.7 is a detail side elevation, looking in the direction of the arrow 7 in Fig. 3.

Referring to the drawings, 1 have shown portions of the frame 10 of an addressing comprises a sten- 1922. se rialuo'. 578,184.

' machineadaptedto operatenpon magazines,

periodicals or other articlesof similar size and shape. Hereafter 1n the spec fication and claims, where the word magazine? is used, it is to" be understood as covering-peri- 'odicalsand other articles-without a'spe'cific definition-thereof. I r I Upper and" lowed' conveyor tapes:

'12 (Fig-1) or'other suitable conveying device's'are provided for feeding the1mag.

zines M'to and from position for. receivingthe a 6,5

address from the correspondingstencil.

The stencils are preferably fed" transversely to the path of-tr-avel of the magazines by; a-'

stencil slide 13 having stencil engaging ledges or projections -13 ,"preferably' beveled rearwardly sd asto slide freely underthe stencils during t'he' return or idle stroke a Thestencil slide l3is connected by: a link 14;-tothe 'upper 'end of a lever lo m'o'unted on a fixed pivo'tT16-l nd'having a pin or stud 17 secured in adjusted position in a in the head 20 of a link or connecting rod 21, whichv in turn is pivoted at 22 (Fig. 1) to a lever 23 mounted'on a fiiied -p1vot2t and engaging aside cam25 on the driving shaft 26. .7 A latch 27 (Figa') is pivoted, at'28 on the head '20 ofthe link 21 andj-is normally 'held' yielding-1y in the position shown in Fig. 4 by a spring29' which holds thel'atch 27 against a stop tion, the latch locks the pin 17 in the outer end "of the slot 19 andthusespin 3O. VVh'en in this "positahlishes operative connection between the cam 25 and 'the" stencil slid'ej13.- The shaft 26 and cam 25 are continuously rotated and the stencil slide is thus given regularly repeated reciprocato-ry feeding able in a g ide late 4.0 (Fig. 3) and is coir nested at its opposite end to a plunger 41 2) on the shaft 33 meshes with a simislot 18 in the lower arrn'l5 (Fig? 3) of the "lever 15. .Thepin 17 extends through a slot 19 (Fig 4) is fixed the latch 27. v

slidable in a fixed block 42. At its intermediate portion, the lever 39 is engaged by a cam 43 secured to a shaft 44 operatively connected to rotate in timed relation with the shaft 26 previously described.

A stop arm or finger 45 (Fig. 3) is mounted on the fixed pivot 46 and is connected to swing with a detector arm 47 to which is secured the magazine engaging feel-er or detector 48. When there is no magazine in ad dressing position, the detector 48 remains by gravity in the position shown in Figs. 2 and 3, with the finger 45 preventing upward sliding movement of the plunger 41 in the block 42, while downward movement is prevented by a stop pin 49 in the plunger, which engages the upper end of the block 42. A spring 50 may be added to accellerate the return movement of the detector 48.

As the cam 43 rotates from the position shown in Fig. 3, the lever 39 swings about its pivotal connection to the plunger 41, from the position shown in Fig. 2 to that shown in full lines in Fig. 3. The stop plate 32 will be simultaneously moved, through the connecting links and gearing described, to the position shown in Fig. 3, thus raising the latch 27 to the position shown in Fig. 5. The connecting rod or link 21'may be thereafter reciprocated by the cam 25 without imparting any movement to the lever 15 or to the stencil slide 13. There will thus be no stencil feed when no magazine is presented in addressing position.

If, however, the detector 48 is engaged by a magazine M, the detector will be moved to the right in Figs. 2 and 3, carrying the stop finger 45 out of the path of the plunger 41. When the cam 43 thereafter rotates, the lever 39 will swing freely about its pivotal connection to the link 38, moving to the position shown in broken lines in Fig. 3 and communicating no movement to the link 38 or through the gearing to the stop plate 32, these parts remaining in the position shown in Fig. 2. The latch 27 thus remains in the position shown in Fig. 4, connecting the lever 15 to the rod or link 21 and permitting the cam 25 to reciprocate the stencil slide 13.

I have thus provided a very simple mechanism which positively prevents a feed of the 1,5eo,e4.1

stencils in the absence of a magazine from position to receive an address.

Having thus described my invention and the advantages thereof, 1 do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim is 1. In a magazine addressing machine, in combination, a stencil feeding mechanism, a disabling device for said mechanism, regularly actuating means to move said disabling device to operative or inoperative positions, and magazine controlled mechanism effective to prevent movement of said disabling device to operative position by the movement of said regularly actuated means when a magazine is presented in an addressing position in said machine.

2. In a magazine addressing machine, a stencil feeding mechanism, actuating devices therefor including a slot and pin connection, a latch for said pin, and means to remove said latch from locking position on failure to present a magazine in addressing posi- LlOll.

In a magazine addressing machine, a stencil feeding mechanism, actuating mechanism therefor, a controlling device for said actuating mechanism including a lever mounted to swing about a pivot bearing, a movable support for said pivot bearing, means to normally look said support, and means to unlock said support on presentation of a magazine in addressing position.

4. in a magazine addressing machine, a stencil feeding mechanism, actuating mechanism therefor, acontrolling device for said actuating mechanism including a lever mounted o swing about a pivot bearing, a movable support for said pivot bearing, means to normally look said support, means to unlock said support on presentation of a magazine in addressing position, and a cam continuously rotated and engaging and moving said lever at each revolution thereof, the movement of said lever being effective to stop the stencil feed only when said movable support is locked.

In testimony whereof I have hereunto affiXed my signature.
